Cannot obtain loader entries

Describe the bug
rebuild boot (or switch) do not create loader entries in systemd-boot

To Reproduce
Steps to reproduce the behavior:

1. install NixOS unstable
2. git clone template branch
3. cp /etc/nixos/hardware-configuration.nix hosts/asus.nix
4. cp /etc/nixos/configuration.nix hosts/configuration.nix
5. import configuration.nix in asus.nix
6. change locale.nix
7. nix-shell
8. git add .
9. backup old config
10. create link nixos --> $pwd
11. rebuild asus test # all right
12. rebuild asus switch #or boot
13. reboot
14. nothing(

Expected behavior
I thought I would get new boot entry. Also, when I restart display-manager system is shutdown.

Additional context
Personal branch
EFI mount on /boot

I think I solved my problem. After rebuild switch need to execute sudo nixos-rebuild boot.
